SUMSS - EXPLORING THE FAINT RADIO SKY

The Molonglo Observatory Synthesis Telescope, operating at 843 MHz with a 5 deg^2 field of view, is carrying out a deep radio imaging survey of the sky south of declination -30deg. This survey (the Sydney University Molonglo Sky Survey, or SUMSS) produces images with a resolution of 43"x43"cosec|dec.| and an rms noise level of 1-2 mJy/beam. The SUMSS is therefore similar in sensitivity and resolution to the northern NRAO VLA Sky Survey (NVSS). We have made a preliminary catalogue of more than 100,000 sources by searching the currently available SUMSS mosaics to a limiting flux density of 6 mJy at dec<=-50deg. and 10 mJy at dec>-50deg. This is an order of magnitude deeper than any previous radio survey in the south. Positions in the catalogue are accurate enough to allow unambiguous optical identifications. Image artifacts have been removed using a decision tree, which correctly classifies artifacts in >95% of cases. All SUMSS data products are made publicly available through the web.
